Fix failing test for loading CSVDataSet from S3 bucket

[jmholzer]

Description

The test for kedro-datasets in the file tests/pandas/test_csv_dataset.py::TestCSVDataSetS3::test_load_and_confirm currently fails for Python 3.10. It only fails if called when all the tests in tests/pandas/test_csv_dataset.py are run. If it is called in isolation, the test will pass.

If the class TestCSVDataSetS3 is moved to the top of the file, so that it is executed (in order) before the remaining tests in the file, the test case will pass. Since this test does not share resources with any other test in the file and also passes when called in isolation, the time taken between fixture definition and running the test may play a role in causing this error.

Context

This bug currently blocks all development work on kedro-datasets.

Steps to Reproduce

1. Checkout the main branch.
2. Navigate to the kedro-datasets directory.
3. Run pytest --no-cov tests/pandas/test_csv_dataset.py

All tests in this file pass apart from TestCSVDataSetS3::test_load_and_confirm.

The following error is produced:

E           kedro.io.core.DataSetError: Failed while loading data from data set CSVDataSet(filepath=test_bucket/test.csv, load_args={}, protocol=s3, save_args={'index': False}).
E           Forbidden
